We have calculated the k-, symmetry-, and layer-resolved density of states (DOS) at k=0 for Pd and Rh (001) surfaces. For the xy and x2-y2 subbands, which do not hybridize with any other low-lying orbitals, the resulting DOS closely resembles that of a one-dimensional semi-infinite chain of nondegenerate tight-binding atomic orbitals perturbed by a repulsive potential at the terminal site. It displays interference induced oscillations and bound states or resonances of particular simplicity.
